Full horseshoe for the Galerkin truncations of 2D Navier-Stokes equations with degenerate stochastic forcing

In this talk, we will introduce the existence of full horseshoe for the Galerkin truncations of 2D Navier-Stokes equations with degenerate stochastic forcing (Hypoelliptic condition). We will also review weak horseshoe and semi-horseshoe. This is based on joint work with Jianhua Zhang.
